BNDER.

Application filed Jane l.,

. Kaas. a `siti- "ig Chi- .iti State et' new and useot which the cago. in the county ot Coon lllim have invented cercain ful lmproven'ients in Binderse vfollowing is a specitication.'

This invention relates to binders tor binding together Sheets oit paper, in boolrs or otherwise, as may be desired, so that the sheets when opened up will lie liat and so that they can be readily removed 'from the binder it desired. @ne object o1t the invention is to provide a very simple. coinslnict and effective binder for this purpose, which has no springs, and otherwise is so arran. il as to be easily operated, but so as 'to be iependable and durable. @ther objects oi: the invention will be apparent troni` a consideration of the accompanying drawings and the descrip-tion thereol".

0f the drawings Fig. 1 is a plan view oit the binder with a portion ot' the outer wall broken away; 2 is a central longitudina-l section ot the binder along the line 2 2 ot Fig. 1; Fig. 3 is an enlarged detail view o'l a portion of 2; Fig. 4 is an enlarged transverse sectional view along the line 4--4 ot Fig. 1; Figs. 5 and 6 are plan views of certain elements ot ythe binder; and F' i* ig. 7 is a modification of? the details shown in Fig. 3.

'lhe binder comprises an enclosing casing consisting oic two elongated segmental cylindrical walls 6 and 7, one of the walls having flanges 8, so that one strip may be slid in the flanges of the other, thus holding the two strips snugly together., and properly enclosing the interior mechanism. This mechanism, comprises an operating and locking member 9, which is slidably mounted in the casing, and has an operating handle 10., by means oiZ which the member may be slid in the casing a limited amount. The handle 10 limits the distance that the member can be slipped inwardly7 and it desired a lug 11 may be formed on'the inner end of the member which, by coming in contact with the stop 12 termed on the wall 7 of the casing, prevents the member irom being pulled out from the casing farther than is necessary to properly operate the device. rlhe operat ing member 9 has fingers 13 liXed on its edges adjacent its ends; and these fingers are arranged to rotate slightly two strips 147 192e., semi no. seal-ros.

which are mounted tor limited rotary movement longitudinally in the casing. Fixed to each of the strips 14 are prongs orsegments oi rings 15./each oi which is so placed with reference to the respective prongs' ot the other strip as to operate in pairs; and said prongs are suitably arranged to open and close as the strips 14 are rotated somewhat by means of the member 9, and thus to hold the sheets ol" paper properly in place or to allow them to be released when desired by opening the rings. llihen the member 9 is forced inwardly the strips 14 will be ro tated so to close the prongs by the fingers 13 pushing downwardly on the adjacent portions 16 which 'form the lips ot the openings 17 in `the strips 14 through which the `fingers 13 pass. And when the member 9 is pulled outwardly the lingers 13 operating on the adjacent lips 18 ot the strips, will torce the prongs open; it being understood that the prongs 15 are lirmly fixed to the respective strips 14 and pass out from the casing through suitable holes 19 in the member 6 oia the casing.

`When the prongs are open or closed the member 9 loclrs them in position. When the prongs are closed the offsetportions 20 et the fingers rest on the lips 16 and thus hold the prongs closed; and when the prongs are open the offset portions 2O lie under the membersv 14 and thus hold the prongs open.

Although l have set forth the details ot the binder which l prefer, yet modifications may be desired in case of' similar binders tor various purposes such as Jor large or small books, and such modifications may be made by those skilled in the art without departing from the spirit ot my invention. 1n certain Cases l have preferred to omit the offset portion 2O of the tingers 13, and form that portion of the lingers straight7 as indicated in Fig. 7. Also it is sometimes desirable to omit the lips 16 and 18, of the opening 17, and form the edges ot the opening 17 as indicated in Fig. 7 the lips being merely the edges ot a slot cut in the edge of the member 14. Also the lug 11 and the stop 12 may be omitted if desired, as the lingers 13 prevent withdrawal of the operating member 9 'from the casing, even when the lug and stop are omitted.

ln order to fasten the binder tothe back of the binder covers I provide lugs 21 on the casing member 7: The interior mechanisIn is all positioned snugly together and enolosedin the casing in such a niarinerthat eiieot tothe rings as they pass into" their closed or open position. v ments will not ordinarily stop partly closed or open,`but will snap into the limiting posilll tions, `thusobviaiting the annoyance resultant -iironi rthe segments being improperlgv placed when the sheets are be removed or opened.. And as this accomplished Without an)T resilient-means the disadvantages 'of sueh means are eliminated.

f l;` claim* as lmy invention: s

In a binder a rotary prong' holder, a pair of lips lxed to said holder, a member mounted for movement parallel with the yaxis rof rotation of said holder, and a'nger {iXed` `to said member and extending at an angle' to said axis ybetween said lips, said fin- Henc'e the seg-,-

ger having a portionA Substantially parallel Wit-h said axlsvarianged' to rest onV one oi said lips when said member is 1n one position,

Y lthereby looking theholder in its Correspond `easing` substantially parallel with and adjacent said holders a pair of lips iixed to each oi* said holders, and a linger' projecting an- Lgularly lrom said member and-passing between eac-h o't` said pairs oi" lips, whereby when said member is moved horizontally said holders are rotated and are locked in the positions assumed.
